tion).This resulted in utilizing 759 deaths for which there was complete data for all covariates/ risk factors considered.While a "complete" cohort approach for risk factor analysis may not be a major limitation, in terms of performing a full due diligence, the corresponding author would like to clarify that he should have included details of the full cohort and description of the missing data in the original paper.
The corresponding author provides updates to the Abstract, Results, Tables 2-4 and Fig 2 to correct these errors.Please see the location of the error, the original text, and the author-corrected text here.
The reduction from 2000-2005 to 2006-2014 is more significant, albeit that the rate levels have come down due to the denominator issue alluded to already.Please see the corrected Table 2.
Fig 2 needs to be updated to reflect the change in the y-axis values, rather than any changes to trend pattern over the period.The authors clarify that secular trend pattern remains the same but the rate value changes due to the use of the incorrect denominator (last episode only rather than full person time contribution under 5 years of age and for relevant age bands within the <5 range).Please see the corrected  Approximately 70 per cent of the neonatal, infant, child and under-five deaths occurred between 2000 and 2005, with households in the poor quintile having a higher percentage of deaths than wealthier ones (57.1% neonatal, 50.6% infant, and 52.2% under-5).The frequency of male deaths was slightly higher than that of female deaths but this difference was not statistically significant (52.1% vs 47.9%; p = 0.484).
Approximately 70 per cent of the neonatal and 60 percent of infant, child and under-five deaths occurred between 2000 and 2005, with households in the poorest quintile having a higher percentage of deaths than children residing in wealthiest households (57.1% neonatal, 50.6% infant, and 52.2% under-5).The frequency of male deaths was slightly higher than that of female deaths but this difference was not statistically significant (52.1% vs 47.9%; p = 0.484).
Results After reanalysis, the major risk factors following multivariable adjustment remain the same with very minor changes in coefficient values and associated population attributable fraction estimates, namely: poverty (residing in a household in the poorest socio-economic quantile), non-piped water source, mother HIV status, mother vital status and period of death (2000)(2001)(2002)(2003)(2004)(2005).In addition, mother vital status was not included in the original multivariable infant model and should have been based on its bivariate association.It is included in the corrected multivariable model and is a significant determinant for infant mortality in Tables 3 and 4. Please see the corrected Tables 3 and 4 It is highlighted in the Discussion that socioeconomic status, source of drinking water, mother's HIV status, and period of death are significant risk factors associated with under-five and infant mortality.The corresponding author would like to clarify that even though the same conclusions still hold based on the corrected findings, socioeconomic status is not statistically significant for under-five mortality following multivariable adjustment for this age band.

Neonatal mortality (N)-refers to the probability of demising within the first month of life Post neonatal mortality (PN)-refers to the difference between neonatal and infant mortality Infant mortality (1qo)-refers to the probability of dying in the first year of life Child mortality (4q1)-refers to the probability of demising between exact age one and five Under 5 mortality (5q0)-refers to the probability of demising between birth and exact age five.
